BIO205H5 Lecture Notes - Lecture 18: Logistic Function, Intraspecific Competition, Carrying Capacity
Document Summary
Competition is a more general form of species interactions. We can use adapt the lotka-volterra models for competition. We can make predictions and test hypotheses about competition. Example; increase in population size causes increase in competition. More mice means less annual growth rate. Predator-prey relationships are special cases of competition. Interspecific because one species prey on another. Organism housing - use silica to build houses. Little pores and structures to make it stable. Quick depletion of silica and synedra has high abundance - means that synedra outcompetes silica. Populations grows very differently of both types. We can use the logistic growth model to describe competition. Carrying capacity is significant in this formula. We have to have measure of how big the population is. This formula has to decrease population of species 1 bc of competition slowing the growth rate (alongside dealing with carrying capacity rate) New formulas; 2 species interaction with each other (species 1 and 2)
